FEATURES
The DCA 1824 is perfect for powering screen channels in small to medium theatres, or for powering mids and highs in tri-amp systems for larger theatres.
DCAs are equipped with a DataPort for use with QSC DCM/DCP - Digital Cinema Monitor; Digital Cinema Processor, a total system solution that greatly reduces labor & wiring costs.
Compact size (2-RU, 14-inch deep) ideal for use in console-mounted sound systems
All models weigh only 21 pounds, for easier racking and shipping.
Active Inrush Limiting won"t blow circuit breakers at turn-on.
Gain control security cover protects amp from misadjustment.
3 year warranty plus optional 3 year extended service contract!
